To aZZ' whom it may concoct/.11 Be it. known that, 1,. FRANCIS- This invention. has; reference to improve ments in insoles;

One object of thewinvention is to provide a novel and economical; insole strip constituted by two membersdiffering in characteristics whereby the respectiive insemhers may operate relatively, said members being a ttachect together in a manner to; furnish a reinforce to resist the drawing outor pullshoe upper are sewed to the insolestrip.

Another object of the invention is to provide an insole strip having an indicator: whereby inthe operation of sewing the welt and, shoe'upper to asole theoperator may follow said indicatou with his eye and there by adjust the parts under operation -toieffeet the formation of the attaching. stitches approximately at or on a predetermined lineof said. insole strip.

ihnother object. of the invention 1sto provide an insole strip ofi textile. material. with -as-ustainiugmember of diflerent material Other objects of the invention will: appear from the,- following description.

The invention consistsin the novel insole strip. t p p t The invention also consists in an insole having the improvech insole strip.

The inventionzalso consists in such other novel features ofconstr-uction and combination of parts as shall hereinafter be more fully described and. pointed? out in the claims.

In. carrying this invention into practice I take a; strip 9 preferably of woven fabric cut on the straight or on the bias and new ing the edges 10 and 11. her L2- has edges-13 and l' hthe edge 13 be ing: located adjacent the edge 11 of strip 9 and is attached to said strip 9 by a line of stitches 15, extending parallel to the edges 11.. and 13 of said respective stripsi) and 12. These sewing stitches 15,1 5 are preferably made with thread contrasting in color with said strips 9 and- 12 or with one of said. strips. When the strips are sewed together The strip memon a sewing. machine the" outer surface of;

the strip 12'sustains the upper surface when the strip is fed through the sewing machine whereby the underside of the stripe) ispro vidcd with looped or engaged; portions of the stitchingthrejad, as; isshown in Fig,- 5'.

The purpose of the strip 9 is toaffond strength to form a union between the insole? and the. upper and. welt of a shoe. llhe puppose of the strip 12 is to afford or facil ate the. upstanding of the strip 9 after its at .35

taohment to the insole whereby hoth pf said. strips Stand 12 may receive the stitches used to. attaclr thewelt and upper thereto. For;

the purpose of sustaining said strip-9 I may prefer to make the strip 12 v of paper and to slightly corr ugate the sam e trzuls versely. as is indicated. at 12-- In some cases I prefer to manufacture the insole strip as shown in Fig.2. ilrwhichthe strip lh is. made offi vjoven material. cut on. the bias or 11513 1119,. its threads extending: d1:

agonally. These strips heingattached'. a

gether sewing stitches 15' placed simi larly to those shown in, 1. andhayin n the same purpose. In the construction shown iIli Fig. 2: it is founqh thatv the bias strip 16 adjusts itself more readily to the sew'lines of stitches Z), I) through the strips 9 and 12 and also through the insole A 7 whereby the-strip 12 is firmly secured in intimate contact with the surface of the in- "In'some cases it is desirable to manufac- I 'ture the insole A of leathercboard or other comparatively stiff material and it is to be noted that after. the sewing of the insole strip .to the insole, the insole A may be shaped to conform to the surface of a last which is made possible by the flexibility of the insole strip.

After the attachment of the insole strip to the sole A, that portion of the insole stripoutside of the line of stitches I) b is turned upward by means of any ordinary lip turning machine or hand implement as may be most desirable, whereby the sustaining strip 12 is located exteriorly of the strip9. I

The insole strip as a whole is at some time treated with shellac or any other suitable stiffening material and the surplus of said shellac or material is drained from the same.

and 1 progressively follows its curvatures during the operation of the sewing machine which sews stitches through said welt and upper and through the upstandlng portion of the insole strip; These sewing stitches draw tightly against the inner surface of the insole strip formed by the strip or member 9 and in the sewing operation the operator' followswith his eye the line of stitches 15, which are noticeable by their contrasting color, whereby he can gage the line of and below the line of stitches 15.. The line of stitches 15 thus constitutes a guide which assists infpre'venting the sewing of the atta'chingstitchesbeyond the upper edge of Copies of thispatent may be obtained for the insole strip or assists in preventing the approach of said attaching stitches so closely to the upper edge of the insole strip as to permit of their being drawn outward through the raw edge of the insole strip.

After the sewing of the welt and upper to this improved insole strip the edges of the upper beyond the line of attaching stitches and the edge of the improved insole lip may be trimmed nearly to the line of stitches 15, whereby the depth of the cavity within said strip may be reduced, thus reducing the amount of filling material necessary to fill said cavity.

Having thus described my invention I claim as new and desire to secure by Letters Patent.

1. An insole having a strip comprising a pair of strip members free at one edge and secured together on a line spaced from the other edge, said members being respectively of woven material and paper.

2. An insole having a strip comprising a pair of strip members free at one edge and secured together on a line spaced from the other edge, one of said members having transversely extending stiffening elements. 3. An insole having a strip comprising a pair of strip members free at one edge and secured together on a line spaced from the other edge, one of said members having transversely extending corrugations.

4:. An insole having a strip comprising a pair of strip members free at one edge and secured together on a line spaced from the other edge, one of said members being of corrugated paper.

5.An insole having a strip comprising a pair of strip members free at one edge and secured together on a line spaced from the other edge, one of said members being of woven fabric having a raw edge and the other said member being of paper, said securing means being sewing stitches looped over some of the threads of said fabric and drawing said threads closely against said paper.
